The nature of' my invention consists in arranging a chuck and socket on a shaft, in combination with a screw-sleeve, surrounding the same, that the operations of cutting screws or nuts, tenoning wheel-spokes, boring, and such kind of work is greatly facilitated, &c.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure l represents a side elevation of my lathe; Fig. 2, a vert-ical longitudinal section; Fig. 3, an end view of the adjustable standard; Fig. 4, an end'view of the chuck on its socket.

A represents my table or frame. t and c', xed standards, in which shaft B is secured in any well-known suitable manner, and working in boxes. C is the chuck, secured to socket D by screw-bolts cl. The socket is secured to shaft by a tapering pin, c, or in any other suitable manner.

regulating or limiting the withdrawal of the shaft, or its chuck and socket or tool held by the same, in the direction of arrow e.

The adjusting of bits of various kinds in the chuck or securing the work in the standard a requires no particular description, such things being well understood by those skilled in the art.

Motion maybe given to the shaft by a crank, or by means of a belt and pulley or any other gearing.

The bit or other tool may be fed up by means of screw-sleeve, which, when retracted, permits the same to be withdrawn. n

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent of the United States, is-

The combination oi' chuck G, socket D, and shaft B with the screw -sleeve E, arranged substantially in the manner as described, and for the purpose set forth.
